HUSDT Perpetual Contract: Humanity Protocol
Humanity Protocol (H) is a zkEVM-based Layer 2 blockchain designed to solve one of crypto’s most persistent challenges: Sybil attacks. By integrating a unique Proof-of-Humanity (PoH) consensus mechanism, the network verifies users as real, unique individuals—offering a decentralized identity layer that enhances security and fairness across dApps.
This makes H particularly valuable for applications requiring human verification—such as voting systems, airdrop distributions, and social networks—without compromising privacy.

- Settlement Currency: USDT
- Contract Size: 100 H per contract
- Price Quotation: Price per 1 H in USDT

Why These Contracts Matter for Traders
The introduction of H, AERO, and SYRUP perpetuals reflects broader trends in the crypto market:
- Rising interest in decentralized identity (H)
- Expansion of Layer 2 ecosystems, particularly Base (AERO)
- Growth of institutional-grade DeFi lending and RWAs (SYRUP)
Each project addresses real-world limitations in current blockchain architectures, making them more than speculative tokens—they represent functional infrastructure shaping the future of digital economies.
Moreover, all contracts support up to 50x leverage, allowing experienced traders to amplify returns while managing risk through stop-loss orders and position sizing. The consistent funding rate model ensures predictability and fairness across all three instruments.
